PENCIL.

To all whom z' may concern `Be it known that we, ELIZABETH DBRIEN and MARIE G. VIERLING, citizens of the United States, residing at Minneapolis, in 5 the county of Hennepin and State of Minnesota, have invented certain new and use- 1 ful-Improvementsfin Pencils; and we do hereby declare the following to be a full, clear, and exact description of the invention, 10.` such as will enable others skilled in the art l to 'which it appertains to make vand use the same.

Our invention has for its object to provide f an extremely simple and highly efficient lead pencil, and to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the j"accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is an elevation of the improved lead pencil;

Fig. 2 is a View principally in longitudinal lcentral section, on an enlarged scale;

Fig. 3 is a 'fragmentary vlew of the inner end of the inner casing removed Jfrom the oiter casing; and

Fig. 4 is a detail view of the lead-holding stem removed from the inner casing, with some parts sectioned. The numerals 5 and 6, respectively;y indicate inner and outer casings telescopically connected with freedom for compound axial and rotary movements in respect to each other. The outer casing 6 has a contracted or ointed e'nd 7 through the nose of which lea may be fed or retracted, as will presently appear. The outer end of the inner casing 5 is circumferentially expanded to afford a holder 8 for an eraser 9, and which holde-r is p'rovidedwith an inwardly pressed annular bead 10, againstrwhich is stoppedthe eraser. A sto shoulder 11 is afforded by the inner end o the holder 8 for engagement with then outer casing 6 to liinit the axial movement of the inner casinA into the outer casing.

On'the inneren #of the inner casing 5 is Serial No. 458,954.

short of the head 13,v at one end, and its other end is extended beyond said pin and provided with a pair rof spring jaws 15 adapted to receive and yieldingly hold one end of a lead 16. The other end of the lead 16 is loosely held and guided in the nose of 'the casing point 7.' The end of the pin 12 affords a stop for holding the lead 16 against inward endwise movement during writing action.

`The lead-holding stem is secured to the inner casing 5 with freedom for wobble movement by insert-ing the same through a washer 17 in the inner end of the inner casing 5 before the sleeve 14 is secured thereto.A To afford a thrust idear-ing for the' lead-holding stem, there,isplaced` in the inner casing 5 a disk 18 against which the head 13 bears and which thrust bearing also holds said head onto the washer 17. Both the washer 17 and thrust bearing 18 are held in posi?- tion by pressingthe inner casing 5 inward to aord annular beads 19.

IIhe ends ofthe inner casing 5 are closed by the eraser 9 and thrust bearing 18 and afford a cell in which spare leads may be kept and which cell is provided with a longitudinal slot or passageway 2() normally closed by the outer casing 6. Obviously, by

`drawing the inner casing 5 out of the outer the frictional engagement between the two casings,`the inner casing may be circumferptially expanded, as indicated at 21 in 'lfghe thrust bearing 18 securely holds the lead holder agfainst endwise movement Vdur ing writing ac 4on and, at thesametime, the lead 16 is he d against inward endwise movement by its engagement with the end of the 'a lead-holdin stem comprising a pin 12\pin 12. The nose of the point 7 is of such having a hea 13, Y upper and lower sur aces,

stem-is folded a sleeve 14 ,that terminates referabl -with curved vsize as to permit the lead 16 to freely move an aroundawhichytherethrough without any friction whatsoeverr and the wobble movement of the lead holder will keep said lead holder and the lead in alignment, so as to relieve any bendeiiicient for the ing of the lead, whichwould break the same.

The above described invention, while extremely simple and of small cost to manufacture, has, in actual usage, proven highly urpose had in View. By frictionally holding the casings with the lead holder in different adjustments, it is possible to dispense with lead-feeding mechanlsm and leadidin mechanism used in commercial pencils.

A separate application having been filed covering the features of construction by which the frictional engagement between the casingsis secured, said features are not claimed in this application.

What we claim is :y

1. A pencil comprising inner and outer telescopically connected casings, a leadholder, and a Washer supported in the inner end of said inner casing, said washer supporting said lead holder with freedom for wobble movement of said lead holder.

2. A pencil comprising inner and outer telescopically connected casings, the former of which has a washer-like inner end, a leadfeeding stem extending through said washerlike end and having a head held between said washer-like end, and a thrust bearing in the inner casingsaid inner casing b/e'ingV free for axial movement in the outer casino 4to feed a lead through the contracted end thereof or retract the same.

3. A pencil comprising inner and outer telescopicall'y connected casings, the former of which has a'washer-like inner end, a leadfeeding stem extending through saidwasherlike end and having a head held between said washer-like end and a thrust bearing in the inner casing, said washer-like end and thrust bearing holding the lead-feeding stem'iwith freedom for wobble movement, said inner casing being free for axial movement in the outer casin to feedV a lead through the contracted endg thereof or retract the saine.

4. A .pencil comprising inner and outer telescoping casings, the former of which has a washer-likeinner end, a stem supported in said washer-like end and projecting toward the outer end of the outer telescoping member, and a sleeve surrounding said stem and projecting beyond the outer end thereof, the projecting vend of said sleeve being formed with spring lead-holding j aws.

5. A pencil comprising inner and outer telescoping casings, the latter of which has a contracted lead opening at its outer end and the former of which has a doubled-wall inner end,` a stem formed with a head secured between said outer end walls of the inner casing, said stem projecting toward the outeIA` end of the outer casing, and a sleeve surrounding said stem and formed with a lead-holding portion extending beyond said stem. 4

6. A pencil comprising inner and outer telescoping casings, -a stem. centrally supported in the inner end of the inner casing and projecting toward the outer end of the outer casing and a slee've surrounding said stem and pi'bjecting beyond the'same, the

projecting portion of said sleeve forming a ELIZABETH OBRIEN. I MARIE G. VIERLING.
